The majority, becasue that are the proper weapons and tactics for that job. Or do we expect the 190F to kill tanks with it's machineguns?
You missed the point I was trying to make. I can easily see people using the 190F as the primary offensive attacker (out of the dedicated attacker aircraft) because it offers the shortest transit times, and the greatest number of options for engagement and egress. The number of people that simply salvo of half of their rockets at one tank, or miss with all the rockets and drop the bomb, and motor for home would give us an indication of
why they're using the 190F8; do they find its weapons more effective when on the offensive (due to the higher number of heavily-armored defensive tanks, and because of its ablity to quickly knock out enemy tanks), or are they simply using it because the IID, Il-2, and B-25H are too slow for them.
In addition to this, we would also get an indication of precisely why its killing more heavy units; is it a combination of higher probablity of encounter and heavier armament, which would indicate that its less because of the effectivness of the F8, and more because it simply has a greater chance to kill these heavies. Or is it being hauled out specificly because of the higher chance of encountering tanks like the Tiger II. Put simply, which came first, the chicken or the egg?
